I spotted it immediately but who am I to interfere with Eric's manipulations, in my view that's what photography is all about, having fun and exercising one's skills creating an image. Combining images and emphasising one aspect is all part of it. Nice one Eric.
Another possible explanation for the slight loss of sharpness in the plane is the pixel size enlargement as the software rearranges the pixels as the second overlaid image to the same grid pattern as the background image, think micro mosaic? Less of an issue with a modern high res DSLR but with the D1's 2.7 Mp it was very evident when I tried similar tricks with almost brick sized pixels. As well as movement, air distortion around the plane, eddies and fast flowing air-pockets must have an effect on sharpness I would have thought, compressed and expanded air create distortion and air shimmies, especially when it's being compressed and expanded when a bloody great lump of metal is being propelled through it at such high speed, think ship and wake?
In mitigation it wasn't actually 2 images. It's just the plane was a lot smaller below the moon. All I did was lasso a section and stretch it bigger upwards, then erase/feather the top edge where the sky overlapped the moon. Crude ...but sufficient for a bit of fun and discussion.
